I think visiting Uni's is a new thing. Back in the day hardly anyone did. I knew one person who went to visit Birmingham. Because they were set on it.
I got Portsmouth through clearing so just arranged a room the week before. Never even visited! Just turned up!
With Bristol for my MA I never even visited either. Just went!
I can't even get Ds1 interested in visiting Southampton! But I will take him. I'm determined
No chance of visiting 4 others! and will tell Ds1 that that's what he's choosing! 
He could do London, if he got top grades. Bath and Bristol ask too much/ too high calibre. Reading? Doesn't leave me with much ; Bournemouth, Portsmouth, Brighton.
Everywhere else is just too far away.
I do think in covid its best to be close.
